EDWIN women, or NEW YORK, N. -Y.', ASSIGNOR 'ro AUTOMATIC vncoinvi'CANNING comrsiviz, or CHICAGO, rumors, AoonPonArioN or ILLINOIS.

To all whom, it may concern Be it known that I, EDWIN Nonroina citizenof the' UnitedSta-tes, residing at New York city, in the county of NewYork, State of New York, have invented certain new and usefulImprovements in 'Machines for Coating Can Ends, of which the followingis a description, reference being had to the accompanying drawing and tothe letters and figures of reference markedthereon.

The invention relates to .new and useful improvements in machines forcoating can ends.

. An object ofthe invention is to provide an intermittently operatingtraveling support for conveying the end to the coating means. A furtherobject of the invention is to v provide a combined rotating mechanism,an

'intermittent feed for conveying the ends to the coating means, andforrotatin'g thesamein contact therewith.

Aturther object of the invention is to provide. a rotating chucktogether with an in termittent feed, carrying supporting-members-adaptedito cooperate with the rotating chuck; V V A furtherobject'of the invention is to providea coating machine with a'plurality ofoperating stations, whereby one layer may be coating" built up. a m

' .A' further object of the invention is to pro- ,vide'a coating machinewith a plurality of coating stations, .andan intermittent feed forconveying the ends: from one station to another and supporting the endsat the stations, during the. coating operation.

A still further object of the invention is to rhvidf a coatin machinewith mechanism P. a

' In carrying out my invention, I have pro- .vided a coating-mechanismwhich consists t each station is a rdtati'ng chuck which may be raisedand lowered as well as rotated. The can ends are conveyed to the coatingstations by an in. termltt'ently perated endless carrier onwhich aremounted spaced supports for the can ends, which are adapted to berotated so that the can end may be revolved, while in contact'with thecoating mechanism. After the support's'are brought to the operatingstations, the chucks are lowered on to the can ends, and revolve thesame with their supports.

The sup orts are preferably mounted so as to yield and are pressed downby the chuck thus carrying the can end 'into contact with the printingwheel.

Referring to the drawings, I will describe sol the-present illustratedembodiment of my:

invention, although it will be understood that minor changes -in thedetails of construction' and the arrangement 6f parts may be madewithout departing from they spirit of my" invention.

Supporting frame.--The various-parts oi the machine are carried by asupporting frame 1, wn.i ch may be of any desired construction. Saidsupporting frame as herein shown is composed of supporting legs 2, 3,1and cross beamed. -Risin from the support-- ing franie'l, are a pluraity' of brackets 5, which carry the main shaft 6, which shaft is.rotated'hy 8. pulley 7,'which in turn is opersteel any desired way.Said pulley 7 iscarried by a cross shaft. geared to shafhfi.

Thesnpporting' frame also carries at eschihb side, as herein shown, abracket .8 which supports a coating tank 9.

Coating wwchtmismr lhecoating tank 9 1 shown in detail in FigsfG to 9inclusive, is

of oblongconstructionand is adapted to receive the coating material. Themach ne herein shown, is provided with twocoating tanks for the reasonthat said machine is constructed so as to be fed by-two operators, and,in certain respects is ,merely a duplicate of the necessary assembledmechanism for '..completely coating a can end.

The coating is applied to the can end by means of a printing wheel 10,which 1s mounted on ashort shaft 11, supported in a *bearing formedin'the cover for the tank 9.

At its outer end said shaft 11.'carries a sprocket wheel 12. The coveralso .carries a depending bracket 13. A feed wheel 14 operates to supplythe printing ,wheel 10 with the coating material, and a feed wheel 15 inturn supplies the coating wheel 14 with maing wheel 15. The shaft- 20 ismounted in a ing wheel, varied so that the thickness 'of the layer ofcoating material conveyed from terial provided there is not sufiicientmaterial in the tank to reach the surface of the coat ing wheel 14.

The shaft 11 cai ries a gear wheel 16 which in turnmeshes with a gearwheel l7"mounted onthe opposite end of a short shaft '18,

supporting the coating wheel '14, ,The gear 17 also meshes with a gear19 carried by a short shaft which in turn su' ports the coatverticallyadjustable bearing 21, which is normally pressed upwardly by a spring22. A: pivoted arm 23 rests against the up er face of the bearing 21,and limits the vertlcal movement of said bearing. A threaded bolt 24extending up through the cover where the same may be readily accessible,bears at its lower end against the arm 23 and by thin ing the bolt inone direction or the other, the position of the bearing 21 may bereadily adjusted vertically and in turn the position of the coatingwheel 15 raised and lowered. The shaft 18 carrying the coating wheel 14is also mounted in a vertically adjustable bearing 25, which slides in aslot formed in the bracket13. A spring 26 engaging the lower face of thebearing 25, normally tends to raise said bearing and an arm 27 limitsits upward movement. A threaded bolt 28 extending also through the coverwhere it may be readilya'ccessible, bears against the arm 27 andascrvesas a means for adjusting the position of the coating wheel 14. When itis desired to increase the thickness of the coating supplied to theend'by the printing wheel,th'e coating wheels 14 and 15 are adjusted bymeans of thebolts 28 and 24, re

spectively, and thus the distance between the coating wheels and alsothe distance be-.

tween the upper coating wheel and the print one wheel to the other, isvaried and in turn ing said adjustment.

thethickness of the coating supplied'to the cover by the printing'wheelalso varied.

-- intewm'ttent feeding me0han'ism.The

can ends arebronght to the coating mech-' anism by an intermittentfeedlng mechanism, which in the present illustration min the form of twofeed chains 29 and 30, (see Fig. 2). The feed chain 29 at the left handend of the machine as viewed in Fig. 1, en-

gages a sprocketwheel 31, while the feed chain 30 engages asprocketwheel 32, (see Fig. 3). These sprocket wheels are splined to a commonsleeve 33 mounted so as to turn freely on the vertical shaft 34. At theother end of the machine,said feed chains are carried by similarlydisposed sprocket wheels 35, which are mountedtoturn on a-vertical vheld in vertical position, and are carried first across one side ofthemachine, and then the other, by the traveling chains. Each of saidbrackets 37 carriesa support 38, for the can end. In Fig. 4, I haveshown one of the brackets and supports as enlarged. The

support 38 has a depending collar 39 resting- 'on a plurality of balls40, which balls in turn rest on a supporting collar.41. It-will' be seentherefore, that the support 38 is so 'constructed that it may be turnedfreely on the supporting bracket 37; A supporting stem- 42 is secured tothe bracket 3-7 by means of a set screw 43, and said stem projectsupwardly through the collar 41, into 'the col-' lar 39. The collars 39and 41are mounted onthe stem 42 so that they may b e'inovedlongitudinally thereof. Any suitable means may be provided for limitingthe upward movement ofsaid collars, and springs 44, 44, are interposedbetween the bracket 37 and the support-ing collar 41, which springsnormally tend to hold the support 38 in its elevated or raised position.

. The object of holding the support normally raised is so that the covercarried thereby may be fed over the printing wheel of the coatingmechanism, without striking the same, and to allow the cover to bedepressed or lowered on to the printing wheel after it is properlypositioned by the feed-' ing mechanism wheel.

The support 38 is provided with a projecting rib 45 on its upper face,-which serves as relative to said printing I a means for directlyengaging and supporting the end; The ,brackets37 are spaced on the feedchains the same distance apart as the distance between the centers ofthecoating wheels so that when one bracket and the supporting membercarried thereby is properly positioned atone coating station,

the other brackets and supporting members are li rewise properlypositioned at the other coating stations- As a means for operatingintermittently the feed chains I have provided the ordinary Swiss stopmovement. The radially slotted stop wheel 46 (see Figs. 2 and is keyedto the lowerend of the sleeve 33 and isopera'ted by a crank disk47-carrying a crank pin 48. The crank disk 47 is mounted on a verticalshaft 49 (see Fig. '1) which at its-upper end carries a beveled gearmeshing with a beveled gear'50 mounted on the main shaft.

; On the rotation of the main shaft 6, the crank disk 47 willintermittently rotate the v stop wheel 46and1n turn'irhpart .to the feedchains 29 and 30 an intermittent movement.

The radial 'slots in the stop wheeLare so disposed that said chains arebrought to restwith the brackets 37 and the supporting 1 members 88 forthe ends properly positioned relative to coating stations.

Mechanism for rotating the ends.-After the endsare brought to thecoating stations by the intermittently operated means, each end isrotated by means of a chuck 51. The chuck 51 (see Fig. 5) iscarried by astem 52 mounted so as to rotate and slide vertically in a bracket 53supported by the brackets 5 carried by the frame 1 of the machine. Thechuck 51 has a groove 54 formed therein' near its outer periphery, whichreceives the usual upwardly projecting rib of the can end. The chuck isrotated by means of a sprocket wheel 55 and a sprocket chain 56 whichengages each of the sprocket wheels 55, carried by the chuck stems. Saidsprocket chain 56 engages a driven sprocket wheel 57, mounted on theshaft 84. The shaft 34 carries a gear 58 near its lower end (see Figs. 2and 3), which gear meshes with a gear 59, mounted on the shaft 49.

As the shaft 49 rotates in .the manner above described, the shaft 34will be rotated within the sleeve 33 of the feed operating mechanism,and independently thereof, thus imparting a continuous rotation to thesprocket wheel 57, and in turn a continuous rotation to each of thesprocket wheels mounted on." the upper end of the chuck stems. As ameans for retaining the sprocket chain 56in cont-act with the sprocketwheels carried by the chuck stems,'

an idle sprocket wheel 60 is located at each side of the machine. andengages the outside" of said sprocket chain. The sprocket chain alsoruns over a second idle sprocket wheel tion.

I and spacing 61, carried by an adjustable bracket 62, by means of whichany slack in the sprocket chain may be taken up. After the can ends areconveyed by the intermittently operat- 'ing feeding mechanism underneaththe chucks, said chucks are then lowered upon the can ends. The stem 52carrying the chuck slides freely through the sprocket wheel 55-, butsaid sprocket wheel is splined to the stem so that these parts rotatetogether. The sprocket wheel is provided with a collar having a slot -63which re ceives a forked arm 64 and holds said sprocket 55 from lateralmovement.

The upper end of the chuck stem has threaded thereon a slotted collar 65which engages the forked end of a lever 66, (see Figs.'1 and 2). Eachchuck is provided with a lever 66 and all of the levers on one side ofthe machine are mounted on a shaft '67 ,while the levers on the otherside of the machine'are mounted upon a shaft 68.- The shaft 67 carriesan arm 69 .(see Fig. l), which at its free end is connected to avertically sliding bar 7 0. The shaft- 68 carries an arm 71 also securedto thesliding member 70. A disk 72having a face cam groove cut thereinis mounted upon the shaft 6,

(see Figs. 1 and i3). The sliding member or bar is provided withavertical slot which engages the shaft 6, and directs the movements ofthe sliding member or bar 70.

Said sliding member. 70 carries a roller 752 which-engages the camgroove in the disk 72.

The cam groove has two concentric portions located at differentdistances from the cen' ter of the disk and as the disk rotates, thesliding bar70 will be raised and lowered and held first in raised andthen in lowered position. This movement of the sliding member or bar 70,will oscillate the arms 69 and 71 which in turn oscillate the shafts 67and 68, thus raising and lowering the chucks so that they arebroughtinto. contact with the can ends on the supports 38, andsaidenlstogether with the. supports are de pressed until the can end carried byeach support is brought into operative contact with the printing rollateach coating sta- Prele'minary cut Zing .(lUi06.-Il1 order to preparethe can end for the seaming rolls. it is very desirable to give to theedge of the can end a, preliminary curl, so that when the end isplacedon the can body and the seaming rolls are brought into contact with theedge thereof, said edge of the, end and the flange of the can bodywillsbereadily rolled intoa seam. This preliminary curlingflof the canend also aids,in.protecting the coating applied to the can end, as itenables theends to be stacked one upon the other and thecurled portionof the end serves as a means for supporting the. end

the same. the adjacent so that the coating on the end is free fromcontact with themetal of the adjacent end.

This preliminary curling'of the edge of the end, is secured by means ofa curling roll 74 5 (see Figs. 1 and The curling roll 74 is located soas to operate upon the end .at the last coating station, before the endis ejected from the machine. The roll is pro,-

--vided with a central groove which engages 10 the edge of the end, andby pressing the roll toward .the center of therotating end, the edge isroiled over into a preliminary curling, as clearly shown in.Fig. 10. Thecurling roll 74 is carriedby a slide 5, mounted in suitable guidingbrackets, and at its rear end said slide is connected to a rock lever76, which carries a roller cooperating with a face cam 77 m0unted on theshaft 6, (see .Fig. 1). The rear end-of the slide 75 has an adjustablebolt 78, (see Fig 2) which is' ed on the end of a or ss shaft 82;. whichcar-- ries a gear 84 meshing with a gear 85 (see Figs. 1 and 2 mountedin turn on the cross shaft 86. Said shaft 86 carries a'beveled' ear 88;

gear 87 meshingnvith a; beveled mounted on the lower end of the s aft34, which is rotated in the'maiiner above; de-' scribed. I i I v Asprocket wheel 89mounted on the end ofthe shaft 86, operates through asimilar train of mechanism, the coating mechanism on the opposite sideof the machme.

Meansfor ejecting the ends from themacha'n'e, After the can ends havebeen prop erly'coated, the chucks 51- are raised from {the ends allowingthe supports 88 to be raised by means of the springs 44, thus'ln'ztmgtheends from the printing rolls. In

order tocause the chuck to be released with certaintyfrom the end,leaving the end upon the support, I- h ve provided each chuck with aplurality of ejec'tors. Each of said ejectors as herein shown,con'iprises-an ejecting-stud 90 (see Fig. 5), which is can ried by afiat head 91 mounted in a recess formed in. the chuck. A spring 92normally holds the ejecting stud so that the same proiQCtS from the faceof the chuck, A screw 93 supports the upper end of the spring. When thechuck is lowered upon the end,

the ejecting studs are forced upward, compressing the spring 92, and assoon as, the

'65 chucks are raised, said springs will. operate 1,oeo,112

upon the ejcctingstuds so as to strip the end from the chuck. v

I prefer to us three ejecting studs which are symmetricall disposed uponsaid chuck; After the chuckis raised from the support and the support israised to its normal position, the spr'dcket chains carry said supportsalong so tha'tthe end carried by the support comes in contact with anarm 94. or a brush 95 (see Figs. 1 and 2) which serve to knock the endfrom the support and said ends drop into any suitable receptacle'.\Vhile I have described the part 38 as a supporting member for the canend, it is ob-' vious that this part'is in ameasurea. rotatable chuckwhich cooperates with the chuck 51 in clamping and, sustaining the canend or can head so that when the can end or head is clamped between therotary holder chucks, said-end or head peripherally pro- 85 jects fromthe edges of the chucks so that the coating roll may be caused to engagethe projecting flange and coat the same. This allows the can orhead tobe firmly clamped between the two rotatable parts so that the machinemay be given considerable speedwithout dislodging the can end, and stillthe-parts of the can end to be coated, project sufficiently to beengaged by the coating roll.

Operation of mac'hinar In the operation of my machine, one operator sitsat each end of the machine, and an end is placed upon the su' port '38which is at an idle station,

-coating station and then to another. As soon as the end reaches thecoating station, the feed chain stops, the rotating chuck 1Sdepressed,'and engages the upper surface of the end, clamping the samebetween the chuck and the support for said end. As the,

chuck is continuously rotated, the can end will at once-be clamped androtated by means of the rotating chuck. The chuck is further depressedso that the end is brought into contact with the printing or coatingwheel, and a thin coating of the-material properly placed upon the outeredge of the end. The chuck is'then raised from the end allowing thesupport for the end to rise 11 to normal position, lifting the end awayfrom the coating wheel, and the feeding mechanism then conveys thesupport forfthe end. together with'the end to the next station, where asimilar operation .occurs g After the end has passed through the va-jrious coating stations, it'is stripped from the -."support in the mannerabove described. At the last coating station, the preliminary I curlingroll is brought into action, which 2 gives to the ed e of the end whenclamped and rotating with the chuck and support, a preliminary curling.Y

Fromthe above description it will be apparent that I hate provided amachine for for bringing coating can ends, wherein the rotatablesupports or chucks for thecan ends are moved laterally from a positionor region where the can end is applied to the chuck, to a position orregion where the can end is coated by a coating roll, and finally to aposition or region where the can end may be discharged. This region ofcoating may include a number of coating stations, or a single station,as above noted.

lVhile I have shown my machine as comprising a plurality of coatingstations, it will be obvious that from certain aspects of the invention,1 may use only a single coating station. l-Vhen a volatile coatingmaterial is placed on the end, it is often desirable to apply a seriesof coatings one upon the other, thus building up a coating which willhave a material thickness. If however, my coating machine was used toapply a coating of different consistency, a single coating station mightbe sufficient for giving to the end a coating of proper thickness.

Having thus particularly described my invention, what I claim as new anddesire to secure by Letters Patent, is
